8.3 Suggestions for Further Research Since the use of parameter-based DSM in building design is innovative, it may trigger further researches in many aspects. Some further research topics are listed below. This dissertation utilized only binary parameter-based DSMs. Further research may be done to enhance the existing models via assigning numerical values to the dependencies. A multitude of attributes that provide more detailed information on the relationships can be provided such as importance and strength of the dependency. Probability of repetition, variability of information exchanged, and the impact of an iteration can also be included in the analysis in order to simulate the modeled processes. Using the parameter-based DSM, comparison of different design configurations is possible. A DSM can be produced for each design option and different designs may be compared in terms of their complexity and how a change in design affects the overall process structure. In this case, the amount of system elements and information flows would be a good indicator of design complexity. When design configurations are compared, their problematic aspects can be identified and new designs can be modified in the light of the gained insights. Incompatibility of building design software was addressed in Chapter 2 as an important information related problem in the industry. Software 189
developers can use the method to integrate separated applications. The flow of information between design software can be effectively modeled using the tool and integrative applications can be developed. This dissertation proposed the integrative use of the parameter-based DSM in combination with the existing methods. This type of use of the method was demonstrated via a simple example in Chapter 5. Further research may exploit this capability of the tool. Last but not least, in this dissertation it was suggested that the method should be utilized as software. Within the scope of this dissertation, only a basic framework was presented for the implementation of such a tool. Further research is needed to develop the tool and to make it available for building design professionals. 190
